STEAM-GENERATING PLANT.

Application mea Maren 1e, 1917. serial no. 155,264.

To aZZ whom z' may concern.'

Be it known' that I, Josnrrr F. SPIEGEL, a citizenA of the United Statesof America, residing in the city of Toronto, county of York, Province ofGntario, Canada, have invented certain new anduseful Improvements inSteanrGenerating Plants, of which the following is a specification.

This invention relates particularly to means for firing locomotive andother boilers so that they will be smokeless in -operation, eiiicientand economical, silent and requiring a minimum` of attention fromfthelireman. i i

I attain my objects by means of the constructions hereinafter describedand illustrated in the accompanying drawings in which- Figure 1 is alongitudinal section showing a locomotive boiler arranged in accordancewith my invention; 1

Fig. 1a shows the tender and its equipment and is complementary to Fig.1;

Fig. 2 a cross section Iof the tender; an

Fig. 3 a front elevation of the tender.

In the drawings like numerals of reference indicate corresponding partsin the different figures. i

The drawings are to a considerablelextent diagrammatical and themechanical constructions may be considerably varied with# out departingfrom the spirit of my invention.

1 is the boiler, which is shown as ofi the lire tube type and providedwith a fluid burner, which is preferably, though not necessarily, with ajet 2 located oppositeeach firetulbe. These jets are each' preferablyprovided with a conical spreader 3 intended to produce a cylindrical jetof flame. Y

Each jet has amiXing chamber l located at its rear end, which mixingchambers com"- municate by means of pipes 5 with altcrnating air and gasconduits Gand 7 supported by a burner framet suitably supported close tothe rear tube `plate of the boiler. Air is supplied to the air conduitsby the `air pipe 42 connected to the conduits and supplied with `air bysuitable compressing means, (not shown).

Gas is supplied from the supply pipe 8 Specification of LettersPatent.`n,

of the type shown and provided Patented Juiy 1,1919.

which connects with each gas conduit and leads from the producer gasgenerator 9` on the tender, whichygenerator is .hereinafter morespecifically described.

In the gas supply pipe and also in the air supply pipe is located amanuallycontrollable valve 10, taneously controlled by asingle handle.In each pipe there is also provided an` automatic4 regulating valve l1controllable by boiler, but as these art, they are not illussteam'pressure `from the are we lllmown in the trated in detail.

y Thetender forms a feed water tank and the generator is arranged sothat it is completely jacketed by the water in the tender, so that thewaste heat from the generator is used to heat the feed water.

The generator is of the hopper type and is provided with sufficientgasspace 12 to give a small` reserve. The gas supply pipe communicateswith this space and preferably forms a coil within the gas space. Afurther reserveltank 43 is preferably provided on top of the tendercommunicating with the gas space 12. n u

`The generator is provided at its lower end with a fire door 13 forre-lightingl, and a longnarrow door 14 through w ich the amined. 15 isthe grate, of any ordinary both arranged to beisimultype, below which islocated a suitable inclosed ash pan 16.V A pipe 17 leads into the ashpit for supplying steam and air to the generator. VViththis pipeconnects a pipe 18, which will lead to anysuitable source of compressedair. f n `With the pipe 17 also communicates a pipe 19 from the boiler.The three pipes 17, `18 and 19 are each preferably provided with Ianautomatic regulating valve `20 adapted to be cont-rolled thereto by thepiping 441-; y

The feed ewater spaceof the `tender is connected by means of a pipe "21with the boiler and an inspirator 22 or Othersuitable device by gaspressure `led 1s used inthis pipe to feed the water to the boiler. Theexhaust steam pipe 23 from the valve chests of the locomotiveleads intothe tender and its upper end isled into a condensing chamber 24:, whichchamber at its lower end communicates by means of openings 25 With theWater space of the tender. A drainage cock 45 is preferably provided inthe pipe 23.

At the lower .part `of. this condensingl chamber I provide a number ofsplash bars 26. These are preferably V-shaped as shown and slightlyclear the bottom When hanging straight. Vhen slightly rocked they actelliciently as splash bars yand at the same timepermit of Water andsediment passing-y f'i'eelyunderneath' tlen When they are hangingstraight. Y

A plurality of clean-out plugs 27 are preferafbly'V locatedl close toythe bottom of the Walls of the t'en'der.

TheA eoi'i'densi'ng"V chamber is provided at its upper end with? alsafety valve 2S', preferably efk ther spring type; tolrelievey any eX-cessi pressure'- W-hieh might accumulatein thechamber. Aimanuallyoperable'valve 29 is;` also. providedby means oft which any pressure maybei relieved and- Which may also beused toB allow any oilE that' mayi-colleet`^-` in tllecondensing chamber to flow out whenrellngstheftender with water.

Y Into the Water space of the-tender extends theillin'gtube 30,-preferably frustoLconical as shown. Thelovver-end of thisl tube isfoiiuuedvvithE a-valve seat-'engageable by the downwardly openingvalve'31, the stem of which is suitably guided. This valve is normally'pressed to its=` seat" bythe coil spring 32 engaging ai supporting `4frame Work' 33 andi the amdersideof theV valve;` This valve vvillffyield! to thel vveight of Water flowing downltliroug'h the filling' tubebut will close to.` prevent'l egress of steamer Water.

Toiindieate" the pressure in the' Water tank I provide the pressure-gage314i communicating Withi the Water'spaee. To indicate gaspressurefLprov-ide theipressure gage 35 communi'catin'g With the gasspace 12. This gas space is alsofprovidedf with a Vsuitable safety valve3.6. to Arelieve excess-.pressure A;z water gage-37 is. alsof preferablyprovided to indicate the water level in vthe tank.v

As the exhaust' steamy is no longer available to create-adraft,l=.provide mechanical means. in connection with the draftpipe 38to create the necessary draft. For this purposelzemploy a fan39iprojectin`g intoV the draft pipe anddrivenby asteam turbineror other:suitablexmotor`v supplied.. With steam fromqthe boiler.

hingeddamper 4'1. is. preferably pro.4 vided at the lovver end ofthe'draftfpipe and may be operatedbyany suitable mechanism.

The operation ofthe plant is .substautiall y as2 follows;V The generatorisstarted in operationfandf suitably' supplied vvithl fuel and any yairand steam ynecessary to satisfactorily start'it in` operationmay besupplied from extraneous sources, after Which it will 4be suppliedy withsteam from the boiler' and with air, as Lmay be necessary,from an aircompressing plant provided for that purpose. As soon as gas isgenerated, it passes away under pressure through the supply pipe 8andgis burned? at the jets 2, thus generating steam in the boiler, theproducts of combustion 'being drawn through the lire tubes preferablybyY mechanically created draf-t as hereinbefore described.

The exhaust steam from the cylinders is ledto the condensing chamber andis there condensed, giving up its heat to the feed Water.Othervvisewaste heat from the generator is also taken up by the feedWater.

To conserve the heat of the feedl Water as mue-h as possible, the tenderis preferably suitably lagged'. As may be necessary feed Water i's addedthrough the filling tube 30 to'replace any Waste, and also as may benecessary oil accumulating iirtlie condensing chamber may be iloatedoifthrough the manually operable valve' 29;

The advantages of the constructions and arrangements I have abovedescribed are numerousbut' it Will: sufice to= enumerate a few of them.In operation the device will be` entirely smokeless,- as the gasgenerated is burnt under conditions which insure perfeet combustiom Theloss of heatin the eX- haust byA radiationy from the irc box iniordinary` locomotives or furnaces is almost en tirely avoided. Thelabors of the fireman are very considerably reducedas the generatoris-self-feeding, and its hoppermay bemcchanically filled or emptied.VVitlrthis device almost any grade of fuelniay be used to advantage. vPerfect regulation of the firing can be= obtained automaticallyI andmanually. The elimination' of the fireboxnot only strengthens theconstruction of the boiler as hereinbefore referred toybut permits of aconsiderable increase-of the-heating surface.:

It Will be understood, of course, ythat the detailsof the constructionmay be very considerably varied Without departiu g from the spirit of myinvention.

l/Vhatf cla-im as my `inveni'fion is:-
